Answer:
1) 0
2) 27/8
3) (-π)³ + 3π² - 3π + 1
4) -27/8
Step-by-step explanation:
1) First we find the zero of x + 1
x + 1 = 0
=> x = -1
by putting x = -1 in the given equation we get
(-1)³ + 3(-1)² + 3(-1) + 1
= -1 + 3 - 3 + 1
= 0
2) First we find the zero of x - 1/2
x - 1/2 = 0
=> x = 1/2
by putting x = 1/2 in the given equation we get
(1/2)³ + 3(1/2)² + 3(1/2) + 1
= 1/8 + 3/4 + 3/2 + 1
= (1 + 6 + 12 + 8)/8
= 27/8
3) First we find the zero of x + π
x + π = 0
=> x = -π
by putting x = -π in the given equation we get
(-π)³ + 3(-π)² + 3(-π) + 1
4) First we find the zero of 5 + 2x
5 + 2x = 0
=> x = -5/2
by putting x = -5/2 in the given equation we get
(-5/2)³ + 3(-5/2)² + 3(-5/2) + 1
= -125/8 + 75/4 + -15/2 + 1
= (-125 + 150 - 60 + 8)/8
= -27/8
